LM4040AIM3-2.5/NOPB

Overview

The LM4040AIM3-2.5/NOPB is a micropower shunt voltage reference from Texas Instruments, housed in a SOT-23-3 package. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.1%. The device features a temperature coefficient of 100 ppm/°C and operates within a junction temperature range of -40°C to +85°C. It supports a maximum shunt current of 15 mA and draws a quiescent current of approximately 120 µA.

Feature Summary

Provides stable precision voltage reference performance suitable for sensitive analog circuits
Designed for low power consumption applications through micropower architecture
Offers high initial accuracy to ensure precise voltage regulation without external trimming

Applications

Portable battery-powered instrumentation requiring low quiescent current
Data acquisition systems needing stable reference voltages for ADCs
Temperature sensing circuits utilizing precision voltage references

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free and RoHS compliance as per manufacturer documentation. Confirm the 'M3' designation corresponds to the SOT-23-3 surface-mount package. Ensure the '-2.5' suffix matches the required 2.5 V output voltage for your circuit design. Check for any recent product change notices regarding manufacturing sites or specifications.

Selection Notes

Select this component when a fixed 2.5 V reference with ±0.1% accuracy is required in a compact SOT-23-3 footprint. Consider the 100 ppm/°C temperature coefficient for thermal stability needs. Evaluate the 15 mA maximum shunt current against load requirements. Compare against the LM4040QIM3 variant if automotive qualification (AEC-Q100) is necessary instead of industrial grade.

Part Context

This part belongs to the LM4040-N series of micropower shunt voltage references. It serves as a drop-in replacement for older two-terminal references like the LM4040AIM3-2.5. The series is designed to provide precision voltage referencing in small packages for cost-sensitive and space-constrained electronic designs.
